Early research

After the war he became a research student at the Cavendish Laboratory, Cambridge University where he studied the scattering of beta particles. In 1922, Schonland returned to South Africa and took up a post at University of Cape Town as a lecturer and later Professor of Physics.

Marriage and children

In 1923 Schonland married Isabel Craib and had one son and two daughters.

Bernard Price Institute

He left Cape Town in 1937 to become the founding director of the Bernard Price Institute of Geophysics at Witwatersrand University where he made significant contributions to the study of atmospheric electricity, photographing lightning and investigating the electric fields generated by thunderclouds. The South African highveld has an exceptionally high lightning incidence which provided abundant material for his work. During this time he spent a scholarship year back at the Cavendish Laboratory, 1927-28.

World War II activity

As a Lt Col, Schonland commanded the South African Special Signals Services at the outbreak of the Second World War and led the development of South Africa's own radar system. In 1941 he went to England to acquire more equipment for South Africa but was requested by Sir John Cockcroft to become superintendent of the Army Operational Research Group of the Air Defence Research and Development Establishment (AORG) at Richmond, Surrey 1941-44. Under his leadership the AORG made significant contributions in a number of fields, especially in the use of radar by the army. By 1944 he was the scientific adviser to Field Marshal Bernard Montgomery with 21st Army Group in England, France and Belgium. By the war's end he held the rank of brigadier.

Knighthood

Retirement and death

He retired to the family home near Winchester, in Hampshire, and died after a long illness on 24 November 1972.

Awards

He was awarded the OBE (military), 1919; CBE (military), 1944; and a knighthood, 1960. He was awarded the Hughes Medal in 1945, the Elliott Cresson Medal in 1950, presented the inaugural Bernard Price Memorial Lecture in 1951 and was invited to give the Wilkins Lecture in 1955. He was an honorary fellow of Gonville and Caius College, Cambridge, 1959-72. In 1999, he was voted South Africa's "Scientist of the Century" and in 2002 he was awarded posthumously the Order of Mapungubwe - Gold class (OMG) for his services to science in South Africa.

Schonland Research Centre

The Nuclear Physics Research Unit of the University of the Witwatersrand, Johannesburg, founded by Friedel Sellschop, mentee of Prof Schonland, was renamed Schonland Research Centre in 1984.
